Thanks for that mate.  I appreciate it big time.  I'll check what you have said out in the morning.  I'm really liking this machine.  Considering its my 1st pinball and I have only had it for 5 days, I'm starting to understand it bit by bit.  When I first opened it up, which I did via trial and error, I thought to myself, what the hell have I got myself into??  But, having made some progress already is great, and in a way I reckon I'll be a bit sad when its all done.  I reckon I like the challenge of doing things I never thought I'd be able to do.  Thanks for your advise!!
